1. 11. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Johanna Bergström; [2023-09-15]
   Nyckelord :Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

   Sammanfattning : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. LÄS MER

3. 12. Relationship between Fatigue Properties and Surface Treatment of Aluminum Alloy

   H-uppsats,

   Författare :Umair Ali Khan; Soroosh Zahedi; [2023-09-14]

   Sammanfattning : Corrosion has posed a significant challenge within the maritime sector for numerousyears. In the 21st century, bolstering the corrosion resistance of alloys, particularlyaluminum alloys, has become paramount. Aluminum alloys find widespread use inpropulsion systems, boat hulls, and cargo vessels. LÄS MER

4. 13. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Jonatan Uusitalo; [2023-08-17]
   Nyckelord :;

   Sammanfattning : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.
